I am using LMS 3.2 and Device Discovery never finishes. It discoevers the majority of devices and then hangs. The only way to stop it is to run pdterm CSDiscovery from the server command line. I used to have exactly this problem under LMS 3.1 and was advised it was a bug and 3.2 would fix it. Discovery has run ok under 3.2 for 6 months but is no longer working.
